There is also Clight (https://github.com/FedeDP/Clight) if you want automatic backlight adjusting given ambient brightness. It supports external monitors through ddcutil C library and has many more features to offer.

Is there anyway I can get a macbook pro 9,2 ambient light sensor working in ubuntu 20.10
Here are two suggestions from the Arch Wiki, try Clight or macbook-lighter. Clight looks to be continuously maintained, so I'd try that one first.

Clight can do that. See the config file.

ambient light - brightness control for Linux
Clight is a lightweight C user daemon utility program that turns your webcam into a light sensor which it depends on to automatically adjust your screen’s display based on ambient light. Just like Redshift, Clight can manipulate the temperature of your screen and it derived inspiration from Calise.

Clight Uses Your Webcam To Adjust Screen Backlight Based On Ambient Brightness.
The only downside to Clight? You need to build not only Clight and Clightd from source, but also 2 dependencies (libmodule and ddcutil), as well as the Clight-GUI if you want to use it. That is, unless you use Arch Linux / Manjaro (there are AUR packages available), NixOS, Exherbo or Void Linux, for which there are packages available.

Connecting a Display Port 1.4 graphics card to the Dell thunderbolt dock WD22TB4
Most monitors have a Virtual Control Panel (VCP), which implements features defined in the Monitor Control Command Set (MCCS). This is a VESA standard. You can find the Input selection command in table 8-10. You send these commands over an I2C bus called Display Data Channel/Command Interface which is yet another VESA standard. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar

Opinions on functional & performance requirements for a desktop TB/USB4 AIC
The protocol is called DDC , it's a VESA standard. In there, it's called VCP features. If you are running Windows https://www.nirsoft.net/utils/control_my_monitor.html will let you use every VCP feature your monitor has. For Linux, https://www.ddcutil.com/ does this. For Mac, https://github.com/alin23/Lunar note how all three mention input selection.

Brightness issue
I've also used ddcui: https://www.ddcutil.com/#introduction, available as an AUR package: https://github.com/rockowitz/ddcutil. This has a nice GUI: https://www.ddcutil.com/screenshots/ddcui_features.png and works on everything I've tried it on out of the box.
